Ain't the gun, it's the shooter.
I've shot a 23 in trap, with my 870, 18.5in barrel, adjustable Knox cop stock (the one that moves), extended mag, cylinder barrel, etc
The really sad part is that's almost my high in trap. :roll:
Shoot what you want, it's all the shooter.
I usually shoot cylinder in one bore and improved cylinder in the other. (SxS)
If i had to pick one, I'd say improved cylinder. You aren't hitting the 60 yard out shots anyway. [poke]
